We carry out a large program to classify newly discovered star clusters from Froebrich et al . ( ( 2006 ) ) in the inner Galaxy . Here , we present a first analysis of a new high-priority globular cluster candidate , FSR 1735 at l =339.1879 ; b = -1.8534 , based on new deep near infrared observations from Sofi at the NTT . A significant peak in the K-band luminosity function is found , which is interpreted as the clump of post-He-flash stars . The distance and the reddening of the cluster are determined to 9.1 kpc and A _ { K } =0.5 mag , respectively , the metallicity is estimated to [ M/H ] = -0.8 . Radial star density profiles are used to measure the core radius and the tidal radius of the cluster . The lack of signs for on-going star formation and the position in the Galaxy pose strong arguments against the interpretation of this object as a young or old open cluster . All the observational evidence is in agreement with the interpretation that FSR 1735 is a so far unknown globular cluster in the inner Galaxy .
